Slightly OT, and I know it varies with the firmness and dampness which can be variable but has any of the gca's here measured the % of upslope that tends to kill approach shots from rolling on the green?
I have seen old men (and now I resemble that remark....) complain about upslopes of as little as 7%, after seeing their ball land and stop, believing they should reach the green. I have also seen a women sort of half top and skitter a shot up a much greater slope of at least 15% in the fw approach. The irony seems to be that a topped shot may go through anything, while a lofted (for senior men) well struck shot may often lose all momentum when it hits the entry fw band to the green. Back in the old days, they put in top shot bunkers to eliminate that "unfairness."
I always wonder about this, because the old RTJ and Wilson style greens, often lauded as "elevated" often had mid slope approaches of 5-15%, obviously with little concern for rolling on by seniors, women, and long approach shots after a duffed tee shot? Historically, I have tended to keep greens as low as possible to both make the run up fw connector function as a run up option, and also, keep long and lateral misses from bounding too far away from the green. However, to my eye those RTJ/Wilson approaches look pretty good, and certainly set up the bunker depth most of us want in gca.
Just asking!
